The females of Calopteryx species look like this.
It is not Coenagrion pulchellum, but Coenagrion pulella. The U-shape on segment 2 and the amount of blue on segments 4-6 point all to C.puella.
Nice photo. But you misspelled the name: it is "Sympecma fusca" *without 'r', not "Sympecma frusca".
Libellula pontica is not an option for Spain. And although it might look alike, there are some differences. Check out the color at the base of the wings. On your photo it is orange, not brown.
Sorry, it's a Southern Hawker (Aeshna cyanea).
The Green Hawker is very rare in Western Europe, appears solely where the Water Soldier grows and looks quite differently.
Nice photos.
It is however not Aeshna cyanea, but something from a different dragonfly family: Gomphidae and I would suggest Gomphus vulgatissimus.
I am not 100% sure of my suggestion, because you might have similar species there, with which I am not familiar.
It is not Sympetrum fonscolombii, the abdomen is too broad for it. It looks more like a Crocothemis species, probably Crocothemis servilia.
Not Anax imperator, but Aeshna cyanea.
